Question

A 80-kg daredevil biker launches himself off of a bike jump of height 4m with a velocity (v) of 30 m/s at an angle of 24°. Neglect air resistance.

a. Calculate the peak height of the biker’s jump (in m).

b. Calculate the range of the jump (in m).

Answer 1

Answer #1

Solution) m = 80 kg

h = 4 m

V = 30 m/s

Theeta = 24°

(a) Peak height , Hmax = ?

Hmax = ( Vsin(theeta))^2/(2g)

Hmax = (30sin(24))^2/(2×9.8)

Hmax = 7.6 m

(b) Range , R = ?

R = ((V^2)(sin(2theeta))/(g)

R = ((30^2)sin(2×24))/(9.8)

R = 68.2 m
